ELECTRIC GENERATOR USING OXYGEN BLOWING COAL GASIFICATION COMPOUND

摘要

PROBLEM TO BE SOLVED: To provide the subject cost reducing generator having a relatively small heat loss and capable of separating and recovering oxygen for a gasification from air by installing a specific oxygen absorbing and separating device into a coal gasifying device for reacting a fuel with oxygen and water in a gasifying oven. ;SOLUTION: This oxygen blowing coal gasification compound electric generator is obtained by installing an oxygen absorbing and separating device 25 using a sodium/ potassium molten salt (A) for separating and recovering oxygen from air [e.g. a device constituted by an oxygen absorbing tower (T₁) 15 for making a contact of the (A) with air for absorbing oxygen, an oxygen separating tower (T₂) 17 for separating the oxygen from the (A) and a mixing and circulating line 20 for circulating the (A) of the (T₁) 15 to the (T₂) 17 through a raw gas cooler 2, 3] to a coal gasifying device 24 for reacting a fuel such as a coal with oxygen and water in a gasifying oven 1 to generate a high temperature gasified gas. Further, the heating and cooling of the (A) is performed e.g. by a heat exchange with a gasified gas flowing through the inside of the raw gas coolers 2, 3 installed by connecting to the gasifying oven 1.;COPYRIGHT: (C)1997,JPO
